Title: Shell mold for forming cylinder sleeve assembly
Inventor: NISHIWAKI TOSHIHIRO
IPC: B22C9/24
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To surely prevent the residual of skin on a cylinder bore caused by curving of a cylinder sleeve assembly. SOLUTION: This forming shell mold D is constituted of an upper mold 1, a lower mold 2 and bore cores 31 -34 having elliptic shape in the cross sectional surface and the major axis d1 of the elliptic shape is arranged along parting surfaces 11 , 21 of the upper mold 1 and the lower mold 2. When the parting surfaces 11 , 21 are curved as the arc-state with the pressure at the time of jointing the upper mold 1 and the lower mold 2, the actual center of each cylinder bore is dislocated to the outside in the curving direction from the rightful position. Even if the center of an edge tool grinding the cylinder bore is positioned at the rightful position of the cylinder bore, since the cross sectional surface of the cylinder bore is the elliptic shape, the sufficient grinding thickness is secured, and the remaining of the scaled surface on the inner wall of the cylinder bore is prevented.

Abstract: PURPOSE:To prevent malfunction and unnecessary operations through the same data is communicated plural times, by preserving just preceding communicated data in an old data preserving buffer and comparing this data with the latest data and performing the processing only when they do not coincide with each other. CONSTITUTION:New received data is compared with old data in an old data preserving buffer 24 by a comparing circuit 26.
